Westlake Chemical Partners LP Statement on Final Regulations Relating to its Qualifying Income Activities

HOUSTON--(BUSINESS WIRE)--

The Internal Revenue Service ("IRS") and U.S. Department of Treasury ("Treasury") today issued final regulations under section 7704(d)(1)(E) of the Internal Revenue Code (the "Code") relating to qualifying income from the processing, refining and transportation of minerals or natural resources, which allows a business to be treated as a partnership for U.S. federal tax purposes.

Westlake Chemical Corporation WLK previously requested and received a favorable private letter ruling from the IRS, prior to formation and initial public offering of Westlake Chemical Partners LP WLKP (the "Partnership"), to the effect that the production, transportation, storage and marketing of ethylene constitutes "qualifying income" within the meaning of section 7704(d)(1)(E).

The final regulations issued today by the IRS and Treasury uphold Westlake's private letter ruling and holds that the Partnership's activities constitute "qualifying income."

"We appreciate the thorough process taken by the IRS and Treasury Department to reach their final decision and are pleased that the final regulations reconfirm and properly recognize these industry practices and remove uncertainty that our activities will continue to generate qualifying income under the Code," said Albert Chao, President and Chief Executive Officer.
